面试时候遇到的一道十进制转十六进制笔试题，顺便记录下来

public class util {

	public static String decimalToHex(int decimal) {
		String hex = "";

		for (; decimal > 0; decimal /= 16) {
			int remainder = decimal % 16;
			
			if (remainder > 10) {
				hex = (char) ('A' + remainder - 10) + hex;
			} else {
				hex = remainder + hex;
			}
		}

		return hex;
	}

}
